What causes a dog's cheek skin to harden and shed like a reptile?

Updated On September 23rd, 2025

Pet's info: Dog | Miniature Schnauzer | Male | neutered | 2 years and 3 months old

My Miniture Schnauzer got a patch on his cheek where the skin hardened and he is now shedding the piece of skin with hair. Where the skin is coming off there is already new hair underneath. It reminds you of a reptile shedding his skin. What can this condition be. It does not fit any description or photo of any of the known skin diseases.

It sounds like he has a hot spot which can be caused by allergies, infections, licking/chewing/scratching, mites/fleas, etc. Have your vet take a look at the area to determine the exact cause. Your vet may need to shave and scrub the area and he may need an oral antibiotic and a steroid to help treat the problem.
